Well i finally got the car i bought put back together, heavily modified 90 talon awd manual. Full race t4 manifold, pt67 turbo, 1000cc injectors, fully ported head and oversized valves, crower 272's and valvetrain, full return style an fuel system with afpr, dual 450's in tank. i just got ecmlink installed and am running SD. I have set the base timing, having trouble getting biss set with the large cams, isc value wont come to roper value. also it wont go closed loop at idle on a consistent basis, brand new 02 sensor. I think it may be the location and the cams. since its a race manifold i had to put the upstream 02 right at the downpipe exit after the turbo. the car idles quite well in open loop, when it does go to closed loop the fuel trims go to -17 and no matter how much i adjust the deadtime, etc, wont change the trims. also the idle goes slightly lower and gets that nice lopey idle. Could I just run an open loop idle? The car is not a daily driver. also when i try to track datalog for the sd table to auto adjust, it says it cant locate the map sensor input, even though i added it to the list and it is there and functioning in the logs, im gonna attach a open loop log and a closed loop for any pointers, very frustrating. weirdly when it goes to closed loop the 02 voltage is like 3.xx volts, thought it should sweep between .1 and .9ish. im an auto technician and its not making sense to me. thanks for any help. have searched alot of different threads, and dont have priveledge to post in tuning section yet.
